SIM DIALOG: Tool for Interactive Narrative Scripting

April 22, 2010

SimDialog is a visual editor for dialog in computer games. With SimDialog, script writers and non-programmers can easily create dialog for video games with complex branching structures and dynamic response characteristics.

A challenge in the design of computer games is writing, organizing, and testing non-linear dialog involving multiple user options and branches to many different possible character responses. The SimDialog system consists of an editor program that allows authors to design complex conversations with multiple options and a runtime component that manages the progression through the conversation during game play.

SimDialog makes it easy for game writers and non-programmers to create dialog for computer games directly without having to edit complex file formats or pass their work to programmers who must then embed the dialog in the game program.

As training simulations and social computer games become more widely accepted as tools for teaching and behavior influence, development must become easier. Tools such as
SimDialog and the experience gained in the program’s development can help to drive development of tools that can help in that process.
